General Information
M6 29 Gauge - 0.014" (0.355 mm) Grain Orientated Electrical Transformer Steel Lamination, RoHS compliant. This steel is used in audio amplifiers, current, output, power transformers; chokes and saturable reactors; and ferro-resonant regulators. The squared hysteresis loop iron-silicon alloy was expressly developed to provide lower core loss with higher permeability in the rolling direction. Grain oriented laminations are supplied in the stress relief annealed condition. The elementary patterns of the crystals in the material are "oriented", or so arranged that the axis of easiest magnetization is nearly parallel and aligned in the direction of rolling. The alignment is accomplished by special cold-rolling and annealing processes. This allows the product to withstand more severe vibration and shock and enables the following:

  1. Lower core losses as a consequence of design.

  2. Higher initial permeability.

  3. Higher permeability at higher inductions.

  4. More stable VA/Temperature relationship over a wide range of ambient temperatures.
